Tetrahedron,1996,52(20):6931-42. | New nitrogenous and aromatic derivatives from Aglaia argentea and A. forbesii[Reference: WebLink] | Seeds and leaves of Aglaia argentea and bark of A. forbesii were extracted. METHODS AND RESULTS:
The known cyclopentatetrahydrobenzofuran derivative rocaglaol (1) and the aminopyrrolidine odorine (5), were isolated together with nine new compounds: didesmethylrocaglamide (6), aglain A (7), Aglain B (8) and aglain C (9), aglaforbesins A (10) and B (11), ethylrocaglaol (12) and forbaglins A (13) and B (14). Compounds 7–11 and 13,14 possess a new cyclopentatetrahydrobenzopyran and benzoxepine skeleton, respectively, linked to an odorine type moiety. All the structures were elucidated notably by 2D NMR spectroscopy. In addition, the structure of forbaglin A was established by X-Ray crystallographic analysis.
CONCLUSIONS:
Didesmethylrocaglamide revealed strong cytotoxic activity against KB cells (IC50 0.006 μg/ml). |
